- To all whom it may concern:

" ment in Lubrication Systems, of which the following is a specification.

My invention relates to luln'ioetors,hnd

more particularly to that type embodying an oil cup, ocrited below the bearing and it wick for feeding the oil. In some classes of apparatus, such, for example, as certain styles oi. ion blowers, the oil cup is frequently located in such a position as to bemore or less inaccessible, so that removal for the purpose of re-filling' is difficult. One object of thepresent invention, therefore, is to provide a convenient means for supplying oil to re-fill such cups without removing the some.

In other types of apparatus, such, for example, as reversible fans used for ventilation purposes, trouble has been experienced with oil cups of the kind mentioned. When such fans are reversed so as to bring the oil cup on top, instead of below the bearing-*the oil soon drains out, with the result that the journal r'dnsdry and is damaged. It is another; object of the invention, therefore, to provlde sulubriccting system for reversible apparatus, of this character, so

designed thatit will operste satisfactorily in either position. J I

In order thg t the i vention may be readily understood, ueiferenc is bed to the accom p'enying drawing, fornfing part of this spec/i through a journal, and oil cup constructed in accordonce'with the first part of my in vention, parts being shown in elevation;

Fig. 2 is a longitudinal section through the some, thewick and swing being omitted;

and-9 v I Fig.3 is an end elevationof a gourn il havin lubricating apparatus arranged in v accor ance with, the second pert of my invention.

Referring to the drawing in detail, 1 designates. the'usual housing and 2 the bearing,

'while 3 indicates theshoft. The housing 1 is provided, at its under side, with the usual boss 1", that is internally screw-threeded to receive the threaded end of an oil cup 4. In this cup is located the usual wick 5 which pro]ects through .an opening 2 in the bearing 2, and which is florced upwardly against the shaft by means of a spring 6. The upper end of this spring is wound tightly about the wick and the lower end rests against the bottom of the oil cup. The,parts so for described are of the usueliconstruction.

My invention consists in the provision of;

this groove in conjunction with the outer well of the bearing 2. If desired, the groove may be formed in the bearing instead of in the housing, the essence of the invention re-' siding in locating such oil duct or channel between the housing and hearing. "A tube 9, or other mczins for feeding oil, may be screwed intothe opening 8, if desired. It will be apparent that oil fed into this-tube will flow around the outside of the bearing 2, through the groove '01? duct 7, and will thus find its way into .the cup 4, from which itiis f6(l llIJWMd tothe'iburnal by the wick, as

' required.

Referring to 3, the construction is the some as in theother figures except that,

oil cup 10, in all respects gfmilar to the cup at. "To accoimhodcte this cup 10, there is, of course, provlded an additional boss 1*, s1m1-.

lsrto the boss 1, and located diametrically opposite the same. In the position-shown in the drawing, the cup 4r} contains the oil and the cup 10 is empty 'the oil being fed upward from the cup 4 y the wick in the usual manner. If, now, the fan or other machine is inverted or reversed, so that the cup 10 is brought underneath, while'the' cup at is on top, the oil will'run from cup in place of the tube 9, I provide-'a'second,

4 through the duct 7, around the outside 'of the bearing into'the cup 10, thus supplying oil which. the wick in cup 10 can feed to the journal.

It will be seen that this arrangement is perfectly reversible and,;operstes' eduelly well in either position, the oil flowing from one cup to the other in accordance with the relative position of the cups. In this way, excessive supply of oil to the bearing and consequent wastethereof is prevented, and, at the same time, proper lubrication is always insured in either running position. It is thought that the many advantages of this simple and efi'cctive arrangement will be readily appreciated without further explanation.

Whatl claim is:

1. The combination with a journal and a journal-box comprising the usual bearing and housing, of an oil cup carried by the housing at one side of the bearing, said housing having an oil li ole formed therein at the opposite side of the bearing, and an oil duct located between said bearing and housing and serving to connect said oil' hole with said cup. I

2. The combination with a journal and a journal-box comprising. the usual bearing and housing, of an oil cup carried by the housing at one side thereof, said housing having an oil hole formed therein at'the opposite side thereof, one of said parts having a circun'iferential groove formed therein adjacent the other part, said groove constituting an oil duct extending from said hole to said cup.

3. The combination with a journal and a journal-box comprising the usual bearing and housing, of an oil cup carried by the housing at one side thereof, said housing having an oil hole at theopposite side thereof, and said housing also having acircumfercntial groove formed in the inner Wall thereof, adjacent the bearing, said groove constituting a connection between'said hole and cup.

4. The combination with a journal and a journal-box, of a separate oil cup carried by the said journal-box, an oil receptacle carried by the said journal-box and diametrically disposed with r .pect to the said oil cup and means for feeding oil from the said receptacle to the said cup.

5. The combination with a journal and a journal-box, of a pair of communicating oil cups carried thereby and located at diametrically opposite points thereof, whereby the lower of the two oil cups supplies the journal in any position of the said journal b x.

6. The combination with a journal and a journal-box provided with a pair of oil cups located at diametrically opposite points thereof, of means for feeding oil from one of said cups to the other, whereby the lower of the two oil cups supplies the journal in any position of the journal-box.

7. The combination with a journal and a journal-box, of a pair of oil cups carried by the said journal-box, one of said cups being located above and one below the journal, means for supplying oil from the lower cup to lubricate the journal, and means for feeding oil from the upper into the lower cup.

8. The combination with a journal and a journal-box comprising the usual bearin and housing, of a pair of oil cups carried by the housing, one above and one below the bearing, means for rupplying, oil from the lower cup to the lllSlt e 'of said bearing. and means for feedingoil from the upper to the lower cup, outside of said bearing.

9. The combination with a journal and a journal-box comprising the usual bearing and housing, said bearing and housing having alined openings formed therein at opposite sides of the jour'nalpan oil cup car ried by said housing adjacent such alined openings at each side of the journal. a wick carried by each cup and projecting through the respective alined openings so as to supply oil to the interior of the bearings, and a duct for feeding oil from one of said cups to the other. v

' 10. The combination with a journal and a journal-box comprising a bearing and a housing, of an oil cup carried by the housing, and means for feeding oil from the cup to the journal, the said journal-box having an oil inlet and a passage leading therefrom to the oil cup.

11. The combination with a journal and ajournal-box, of a pair of con'imunicating oil. cups carried by the said journal-box and located at diametrically opposite points thereof, and meansassociated with the said oil cups for feeding oil to the said journal.

12. The combination with a journal and a journal-box comprising the usual bearing and housing, of a pair of oil cups carried by the said housing, one above and one below the bearing,- means associated with the said oil cups for supplying oil to the inside of the said bearing and further means for feeding oil between the said cups outside of the said bearing. 7
